VALVE FOR HYDROCARBON-RESERVOIRS.

SPECIFICATION forming part of Letters Patent N 0. 561 ,326, dated June2, 1896.

Driginal application filed s t be 16, 1891, Serial No. 405,832. Dividedand this application filed December 8, 1893. Serial No. 493,101. (Nomodel.)

To all whom it may concern:

Be it known that we, JOHN A. LANNERT and WILLIAM R. JEAvoNs, citizens ofthe United States, residing at Cleveland, in the county of Ouyahoga andState of Ohio, have invented certain new and useful Improvements inValves for Hydrocarbon-Burners5 and we do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which itappertains tomake and use the same.

Our invention has reference to valves and reservoirs for liquidhydrocarbons; and our invention consists in a novel arrangement andconstruction of the several parts whereby the guide for the valve-stemis brought into positive and perfect alinement with the valveseat, thusinsuring a perfect seating of the valve and preventing leakage, all in asimple, inexpensive, and positive manner, substantially as shown, andparticularly pointed out in the claims.

This invention is a division of our application, Serial No. 405,832,filed September 10, 1891, in which the carbureter is the subjectmatterof invention and which forms no part of the present application andpatent.

In the accompanying drawings, Figure 1 is a sectional elevation of areservoir and of our improved device in operatin g position therein.Fig. 2 is a central sectional elevation of the said device, showing thevalve-bracket soldered to an ordinary screw-cap of commerce and detachedfrom said reservoir.

It has been found'in practice that if the valve-stem is not held at aright angle with the valve-seat the valve will be leaking andineffectual. I

In ordinary valves of this nature the valveseat and supporting-bracketare made of separate pieces, and the proper adjustment of the partsrequires a high degree of mechanical skill.

By our method the valve-scat, upright support, and lug for supportingthe valve-stem are all formed from one piece of sheet metal by press anddie work, which, while being wholly inexpensive, brings the parts intoabsolute and proper relation to each other to produce the condition of aperfect valve in each instance.

The bracket II is made of sheet metal. Its lower portion is bent atrightangles, and in this portion is formed a seat for valve D. The

upper portion of the bracket h is also bent at right angles, the holetherein for supporting the valve-stem 61 being brought into exactalinement with the valve-seat in the lower bent portion.

In making this valve a strip of sheet metal is first blanked out toproper shape. \Vhile still a fiat piece it is put into a proper gage andboth the hole for stem 01 punched and the seat for valve D formed by asingle operation, which locates these points absolutely alike in everyblank. Next the blank is laid as a bridge over a channeled die, the holeat one end and the valve-seat at the other end of the blank engagingwith suitable guides to positively and absolutely fix the position ofthe blank over the channel. A punch which nearly fills the channel nowforces the central part of the blank-into the channel, the two ends ofthe blank being forced up by the edges of the channel to parallel eachother at right angles to the body of the blank bring the hole on the oneand the valve-seat on the other in perfect alinement. The valve and stemcan then be inserted into proper position in the bracket by slightlyspringing the upper end of the bracket, as shown by dotted lines.

The valve is compact'and light and may be soldered in an ordinaryscrew-cap of commerce, as shown.

That we claim is 1. In a valve for liquid-reservoirs a bracket formingthe valve-seat and support for the valve-stem formed out of a singlepiece of sheet metal, substantially as described.

2. In a valve for liquid-reservoirs, a single piece of sheet metal bentat one end to form a valve-seat and bent at the opposite end to form asupport for the valve-stem, substantially as described.

3. In a valve for liquid-reservoirs, a single piece of sheet metalhaving a valve-seat at one end and a support for the valve-stem at theother end and bent to bring said seat and said support into alinement,substantially as described.

Witness our hands to the foregoing speci fication this 2d day ofDecember, 1893.
